RTC2.0-Saving Workitem throws error -JazzUsers role

Hi,

We are connected to LDAP user registry! We mapped JAZZ group JazzAdmins and JazzUsers to LDAP groups JazzAdmins=TestTACAdmin92 and JazzUsers=TestTACUser94.We have no problem loggin in. But when a person in JazzUser group tries to save a workitem, an exception is thrown with msg,

The user "<user>" is not authorized to perform the operation. The "JazzUsers" role is required to perform this operation.

Note:This user is a member of the JazzUsers group.

Also we observed that a User in JazzAdmins group is able to save a workitem.

Can anyone help me on this asap.

Thanks in advance,
Mala
